"But one thing I did before I left, Harry Reid is actually a friend of mine, and he and I agreed to read each other's book over the break," DeMint said. "So I read his book, and it gave me a little insight into how my opponents think."

DeMint published "Saving Freedom," about stopping America's "slide into socialism, last month. Reid published "The Good Fight," a somewhat autobiographical tome, last May.

"So hopefully he'll read my book, and we'll get a chance to talk about it," DeMint added, explaining that he'd given a copy to each Republican senator as well.
